Preparation and Sustained-Release Properties of Panax notoginseng Leaf Saponins-Loaded Multi-Walled Carbon Nanotubes/Chitosan Composite Gel
: To address the intrinsic drawbacks of pure drug-loaded chitosan hydrogels—namely poor mechanical strength, severe initial burst release, and insufficient structural stability—this work developed a multi-walled carbon nanotube (MWCNT)/chitosan composite hydrogel loaded with Panax notoginseng leaf saponins (LPNS).
